Overheating is a really serious problem for dogs in the summer months, and it is important for us to make sure our pets are comfortable when we are not around. I always leave fresh water out for the dogs and leave a fan on in the house when I am away. I also keep their car rides to a minimum during the summer - and never, ever leave them in the car while I run into a store. What does everyone else to to ensure the health of their pets during the summer?
